These still have the bug with Photoshop on Win 8 where the background flickers when zooming in/out and doing other stuff.

These also wont install the HDMI audio driver for me. It fails. This is an old bug i used to have on Win 7 many months ago, but the last few driver versions haven't had it on either Win 7/8. Now AMD have manged to bring it back. Great.

After upgrading from the previous drivers the 13.1's also completely screwed up after a system restart, so i had to uninstall all AMD drivers, then re-install.

Was hoping that driver quality would finally improve now AMD don't release them so often, but guess not.Reply

I tried to Crossfire two 7950 cards and the performance was terrible. Onto the web... A whole load of people with the same issue, so, I changed the motherboard. Same issue. I gave up, sole them, threw in 2x 660 cards and all was well.

Why do I have to edit the registry to stop one card turning off? Why do I have to create profiles? This was the first and last time that I built a performance rig with the gpus based on AMD

ULPS is designed to reduce power consumption when you are in 2D mode. The card kicks back in when you go into 3D. It's a godsend when I'm testing 4-way and have to manually jack up the fan speed so the 7970s don't get blistering hot during a game test.

Dealing with more than one card in a game engine is tougher than most people realise. You either use both cards to render the same frame (involving splitting the buffer and causing crosstalk), or use the cards to render alternate frames (again causing crosstalk to update memories) which is difficult if one card starts to lag behind. This is usually fixed using clever algorithms in the driver to adapt, but it tends to be done on a driver by driver basis.

A good test is Dirt3 - if it doesn't work there, it doesn't work anywhere. Going from one 7970 to four, I get the following from an older test:

Dirt 3 - One 7970: 73.95 FPSDirt 3 - Two 7970: 136.28 FPS (+84.3% of a single card)Dirt 3 - Three 7970: 195.11 FPS (+79.6% of a single card)Dirt 3 - Four 7970: 237.40 FPS (+57.2% of a single card)

On the same older drivers, Civilization V performs badly:

Civilization V - One 7970: 78.73 FPSCivilization V - Two 7970: 83.13 FPS (+5.6% of a single card)Civilization V - Three 7970: 82.50 FPS (-0.1% of a single card)Civilization V - Four 7970: 83.00 FPS (+0.1% of a single card)

With the newer drivers, Civ V performs better as it got added. These are the dangers of using a multi card setup - waiting for your game to get a proper multi GPU profile. If the game is AMD or NVIDIA 'enhanced', then it'll probably get the multi-card profile before the other company.Reply

I never experienced any 'issues' in Windows 7 (or games) with 12.11 Beta, so this WHQL seems to be the same thing, just with AMD's final stamp of approval.

Far more exciting is the forthcoming 13.2 Beta - an incomplete version of which has already been leaked - which is reported to address frame latency issues in certain games. It's not clear to me whether this Beta will only address frame latency in SINGLE-GPU configurations or whether Crossfire-induced microstutter will also be mitigated

(and no, before you ask, the 'dynamic vSync and frame-limiting tools in the latest preview of RadeonPro do NOT mitigate the problem as much as the reviews claim)Reply

After updating to 13.1 last night I noticed Adobe After Effects lags a lot on my Win 7 64-bit computer with ZDFC XFX Radeon 6870. I have OpenGL enabled and prior to updating my video drivers I actually had it disabled. I noticed a big performance change for the better when I enabled it specially in RAM previews and Rendering.

Now it seems to be behaving as previous disabled OpenGL state even though it's enabled. Will have to troubleshoot more.Reply

is the output of 5.1 sound over HDMI enabled in this driver? I remember last year that I only could output 2.0 sound on my old 5770 card. it's time for an upgrade, so it would be great to know if it is finnaly working.

Sounds like the graphics card only sees the stereo channels of the TV and not the AVR it eventually ends up in. Why not just plug the PC HDMI into the AVR since the AVR should be connected with the TV anyway? :)Reply

That's because my AVR is integrated with the bluray player. It only has 1 -archdmi-arc connection. If it had another hdmi input this would be a lot simpler. But the xbox works with 5.1 over arc. There is no reason a pc shouldn't.Reply

That's the screen rez ( when they aren't in 6 monitor mode) and one of the games the two amd catalyst writer employees love to play, so you got lucky they made certain it worked so it didn't cut into their game time.Well, one down, 257 to go.Reply

I upgraded this driver in windows from inside CCC. Then rebooted to a stop error about a hardware change so I was like wtf. I had to run a windows repair which corrected something on boot that the driver changed!!!!!

Anyways once I got back into windows everything was fine and 13.1 seems stable. I think i'm gonna go back to uninstalling previous drivers then installing new ones. And not just do it over stop which has been working fine forever.Reply

I downloaded this yesterday and attempted to update twice and both times came out in me have to do a system restore with a proper working display driver. I don't know if anyone else is having this issue but I'm sure it can't just be me. This is the first driver i've had that caused my computer not to properly boot up.Reply

Installing the 13.1 Catalyst fails on my 7850 on Windows 7 64bit and requires a system restore. I tried a clean Windows install - same issue. Looked in the driver package .INF file for Windows 7 64bit - it does NOT contain any info for GCN-based cards! (The files for 32bit, and for 64bit Vista and Win8 are fine)

They've majorly screwed up the release, do not install for GCN-based cards on Windows 7 64bit until they have corrected this and re-released it. This is reported as well in the AMD forums.Reply

I tried installing this twice yesterday once again and it caused the same issue as it did the first day the update came out. It cause my display driver to crash and computer would not boot up. My friend has a 7790 and a more updated computer than mine and same issue came up with his. I just hope amd fixes these bugs in their updates.Reply
